Improvement in retorts for the manufacture of gas from wood



UNITED STATES MARK LEVY, OF

IMPROVEMENT INRETORTS FOR THE I PATENT YOFFICE.

NEY YORK, N. Y.

MANUFACTURE 0F GAS FROM WOOD.

' that thev following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure I represents a vertical cross-section of the retort and oven. Fig. II shows a vertical longitudinal section of the same.

Similar letters designate the same parts.

The nature of my invention consists in the construction of a retort in combination with un removable reheatingilues, whereby a large surface is exposed to the heat, combined with great strength and durability, at the same time accomplishing a more perfect and complete combination of the gaseous matters.

In the accompanying drawings, Ais the retort formed in the elliptical shape in crosssection and of any length desired, and placed on its ends with its longest axis perpendicular. This retort is set in brick-Work B of any suitable arrangement over a furnace O. The smoke or gases from this furnace escape through the flue D.

The elliptic retort is divided by a series of Iiues E E E2, &c., into two parts. G is apipe connected with the top flue E to lead the generated gases away from the retort to be purified.

The retortAis filled on both sides with wood or similar Vegetable substances, from which the illu minating-gas is to be generated. The generated gases pass then through the openings m, forming a communication hetween both parts or sides of the retort and the central tlues into said tlues and circulate back and. forth through these iiues E E E2 E3, the., and are finally led away to be puriiied by the pipe G. the retort being high and narrow, exposes a large extent `of heating-surface and insures great durability. The lowest iue E, being directly exposed to the fire, will partially convert the produced tar and pyroligneous acid into gases, mixing the same with the other generated gas and increase thereby its illuminating power, while the remaining ues obtain only their heat from the surrounding retort, and can consequently never become generated gases passing through the same.

That l claim as my invention, and desire to secure by Letters Patent, is-

The arrangement and use of the ellipticshaped retort A, with the central unremovable reheating-ues E E E2, &c., dividing said retort into two parts, constructed and combined together in the manner and for the purpose substantially as described.
